Introduction to Psychology

• Psychology aims to understand the reasons behind human behavior in various situations.
• Unlike common speculation, psychologists employ systematic and scientific methods to answer questions about behavior.

Nature of Psychology and its Definition

• Psychology is defined as the systematic and scientific study of mental processes, experiences, and behaviors (both overt and covert).
• Historical context includes:
  • Indian psychology: Explored concepts of soul/spirit since the Vedic and Upanishadic periods; various schools like Yoga, Samkhya, Vedanta, Nyaya, Buddhism, and Jainism contributed insights on the mind.
  • Modern psychology began in India at Calcutta University in 1916 with the establishment of the Department of Psychology.
  • Western psychology formally began in 1879 with Wilhelm Wundt opening the first experimental laboratory at the University of Leipzig, Germany.

Components of Psychology

Biological Perspective

• The study of human behavior starts with the biological system, examining:
